摘  要:
[目的]研制20%异噁唑草酮悬浮剂的最佳配方。[方法]采用流点法初步筛选20%异噁唑草酮悬浮剂的润湿分散剂,在此基础上,使用激光粒度仪测定粒径的方法对分散剂进行进一步的筛选。[结果]综合对比2种方法的筛选结果,优选出20%异噁唑草酮悬浮剂的润湿分散剂为SP-SC3266。实验结果显示,SP-SC3266冷热贮藏稳定。[结论]通过对润湿分散剂、增稠剂、抗冻剂和消泡剂的筛选,确定20%异噁唑草酮悬浮剂的最佳配方:原药20%、润湿分散剂SP-SC3266 4.00%、黏度调节剂黄原胶0.20%、防冻剂丙二醇4.00%和去离子水71.30%。该悬浮剂的悬浮率达94.30%以上,且冷热贮藏稳定。

摘  要:
[Aims] The best formula of isoxaflutole 20% SC was developed.[Methods] Wetting dispersant of isoxaflutole 20% SC was selected by flow point method and further select was conducted by laser particle size instrument.[Results] The experimental results for the two methods showed that SP-SC3266 dispersing agent can be processed with good flow behaves.The dispersion stability of SP-SC3266 during heat storage and frozen storage was good.[Conclusions] Isoxaflutole 20% SC was formulated though screening surfactants,thickeners,antifreezes and defoamers.The formula was isoxaflutole 20%,SP-SC3266 4.00%,xanthan gum 0.20%,propylene glycol 4.00%,deionized water 71.30%.The suspension rate of product was over 94.30%,stable after cold and hot storage.
